Plot

The plot involves the discovery of a mysterious torpedo found on the shore of Benbecula. A Naval team descends on the area to deal with the torpedo accompanied by Nicolson, an intrigued security officer. Further investigation of the torpedo reveals an international spy kit, the contents of which include a Finnish passport, British and Swedish currency, and most intriguing of all, a fragment of sheet music.

Nicolson is joined by fellow security operative Grant, and together they investigate the sudden appearance of the torpedo. Their investigations meet with resistance from the locals, and when their investigations lead to a murder, it becomes apparent that someone is trying to conceal something sinister. As Nicolson comes close to learning the truth, he is lured into a trap and is injured. When he comes to, he discovers that Grant has been murdered and he endeavours to find the people responsible. He eventually uncovers an elaborate espionage operation.

Theme

While the show is no longer seen, the theme tune remains a favourite with Scottish musicians, mostly accordionists and pipers. This beautiful air was originally called "Dr Mackay's Farewell to Creagorry" by its composer, Iain MacLachlan. David Silver of Glasgow wrote the most common and famous words to the song.
